Looks good

The address is syntactically valid and not on our disposable list. Note: actual deliverability requires a DNS MX lookup, which the browser cannot do directly.

About MX records

MX (Mail Exchange) records tell senders which server accepts mail for a domain. Browsers cannot perform DNS lookups directly, so this tool uses a static table for the most common providers. For full MX verification, run dig MX example.com in a terminal.
